Travelers on the Okayama to Tokyo route can utilize the Shinkansen service, primarily served by the Nozomi and Hikari trains. The Nozomi Shinkansen is the fastest option available, with speeds reaching up to 300 km/h (186 mph) and completing the journey in approximately 3 hours and 30 minutes, benefiting from fewer stops. The train typically halts at major stations such as Okayama, Himeji, and Shinagawa.
On the other hand, the Hikari Shinkansen, which also serves this route, takes around 4 hours as it stops at additional stations, providing access to a wider range of areas along the way.
Both services feature Ordinary and Green Class seating, offering different levels of comfort. The Nozomi is preferred for its speedy performance, making it suitable for travelers prioritizing time. Conversely, the Hikari, while slightly slower, offers more regional connectivity and remains a comfortable option with ample facilities onboard.
